BINDER Filed DBG. 50, 1936 ATTORN EYS 'Patented Sept. 26, 1939 UNITED STATES PATENT OFFICE 1 Claim.

The invention relates to binders and more especially to loose-leaf binders or covers.

The primary object of the invention is the provision of a binder or cover of this character, wherein through the use of hinged members books of varying thicknesses or folded leaves may be conveniently inserted and held so that the pages of the book or the folded leaves can freely swing to have full opening of such book or leaves when within the binder or cover Without liability of the leaves unduly bulging or the book `accidentally freeing itself from the cover or binder during the use thereof.

Another object of the invention is the provision of a binder or cover of this character, wherein magazines, pamphlets, or loose folded leaves can be held so that the same may be easily manipulated and also such inserted matter conveniently removed yet will not become accidentally detached from the binder or cover.

A further object of the invention is the provision of a binder or cover of this character, wherein matter inserted therein involving leaves will assure free oscillation of the leaves, the binder or cover being a temporary one and assures protection to its contents.

A still further object of the invention is the provision of a binder or cover of this character, wherein periodicals and paper or cloth books can be conveniently held and handled, avoiding the soiling of the outside covering of such periodicals or books when contained within the binder or cover and enabling the leaves of such periodicals or books to lie at on the opening of the same.

A still further object of the invention is the provision of a binder or cover of this character, which is simple in construction, thoroughly reliable and effective in operation, neat in appearance, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, which discloses the preferred embodiments of the invention and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is an elevation of a binder or cover constructed in accordance with the invention and showing a paper covered pamphlet or book held therein.

Figure 2 is a fragmentary elevation with the insert removed showing the hinge pintles by full lines in one position and by dotted lines in another position.

Figure 3 is a vertical transverse sectional view through the binder or cover.

Figure 4 is a top edge view.

Figure 5 is a view similar to Figure 4 showing the insert held within the said binder or cover.

Figure 6 is a View similar to Figure 1 showing a. slight modification.

Similar reference characters indicate corresponding parts throughout the several Views in the drawing.

Referring to the drawing in detail, particularly Figures 1 to 5 inclusive, the temporary binder or cover comprises in cooperation a back A and op.- posite sides I hinged thereto thus forming a file binder or cover. If desired the sides I may be relatively flexible and made from any suitable material which also may be integral with the back A. In this instance the outer edges of the sides I are reinforced at 2 which reinforcement is carried over the edges of the back A for giving strength and wearing quality to the binder or cover.

Longitudinally disposed along the inner face of the back A is a flat metal strip 3 which has bent outwardly therefrom spaced bearings or ears 4, these being preferably located next to the top and bottom edges of the said back A while journaled in these bearings are freely swinging retaining members in the form of hinge pintles 5 which in this instance are bowed toward each other and are crank terminaled for offsetting the pintles 5 in the hinged mounting thereof.

The strip 3 at opposite ends is bent on itself to form hook-like jaws 6 which are trained about the opposite ends of the back A and clinched or otherwise made secure thereto so that the strip will occupy a central position longitudinally of this back along the inner face thereof.

Radially insertable between the strip 3 and the pintles 5 are the outside cover sections 8 of a book, pamphlet or the like having the permanent leaves 9 at their bound edges located between the two rods 5 so that this book as a unit will be temporarily held in place and both the cover sections 8 and the leaves 9 thereof will be freely hinged within the binder or cover to permit the free opening of the book and the turning of the leaves with the result that when the book or the like is opened such leaves and its permanent cover may be laid flat upon a support or in such condition held by a user thereof.

In Figure 6 of the drawing there is shown a slight modification wheren the pintles 5 throughout the major portion thereof are straight in contradistinction to being curved similar to the pintles 5 hereinbefore described and these pintles 5' are crank terminaled and pivoted for swinging motion.

From the constructions hereinbefore described the contents of the temporary binder or cover will be loosely hinged therein resultant from the manner of construction of the pintles 5 and 5 and the pivotal support of the same at the crank terminals thereof.

The contents of the temporary binder or cover will be protected in its use and the free swinging tent be a book, will be assured of such binder or cover.

What is claimed is:

A loose leaf binder for a bound book having outer cover sections and permanent leaves, comprising a supplementary eXible protective cover having a permanent back and sides, a strip having separable clamping engagement with said back, ears bent outwardly from said strip in close relation to the clamping engagement to the latter with the back, and swingable wire-like bars having outwardly directed crank ends journaled in the ears for engaging said bars with the outer cover sections outwardly of the leaves of the permanent book.
